Tg Pro (temperature Gauge Pro) — 2.50

Ability to monitor and manually boost fan speeds.

Built-in checks to see if sensors or fans were failing.

As Apple transitioned from Intel to their own silicon (M1, M2), users found their new machines to be incredibly efficient but still capable of running hot under heavy loads like video editing or compiling code. TG Pro (Temperature Gauge Pro) 2.50

While Apple Silicon ran cooler, users still faced thermal throttling, and the default fan control was designed for silence, not max performance. Furthermore, specialized new hardware (like M1 iMacs and early M1 Mac minis) needed tailored monitoring.

The updates surrounding 2.50 focused on unlocking that potential. It brought full support for M1 Macs, offering more temperature sensors than any other app—including GPU, CPU, SSD, and battery. Ability to monitor and manually boost fan speeds

TG Pro continued to iterate heavily after this version to support M2, M3, and now M4/M5 chips, but the 2.50 era established it as a must-have utility for the early Apple Silicon adoption phase. Tunabelly Software Blog

The core story of this version was its enhanced Auto Boost feature. Users could set custom fan rules to boost speeds before the Mac became too hot, maintaining peak performance during intense workflows. Key Features Highlighted in this Era While Apple Silicon ran cooler, users still faced
